In this article, we are going to set the minimum scale limit in a canvas line in FabricJS. The canvas line means the line is movable and can be stretched according to requirements. Further, the line can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.

Syntax:

fabric.line({
    minScaleLimit : number
});

Approach: To make this possible we are going to use a JavaScript library called FabricJS. After importing the library, we will create a canvas block in the body tag which will contain the line. After this, we will initialize instances of Canvas and line provided by FabricJS and set the minimum scale limit in the canvas line using minScaleLimit Property, and render the line on the Canvas as given below.

Parameters: This function accepts a single parameter as mentioned above and described below:

  • minScaleLimit : It specifies the minimum scale limit. It contains a numerical value.

Example1:

HTML




<!DOCTYPE html> 
<html
  
<head
     
   <script src
   </script
</head
  
<body
   <h1>fabric.js | line minScaleLimit property</h1>
   <canvas id="canvas" width="600" height="200"
      style="border:1px solid #000000;"
   </canvas
     
   <script
        
   
      var canvas = new fabric.Canvas("canvas"); 
  
   
      var line = new fabric.Line([150, 10, 220, 150], { 
         stroke: 'green',
         minScaleLimit  : 1
      }); 
   
      canvas.add(line); 
  
   </script
</body
  
</html


Output:
